稀土硝酸盐与N,N,N’,N’,-四正丁基己二酰胺配合物的红外和拉曼光谱

INFRARED AND RAMAN SPECTRA OF LANTHANIDE NITRATEBINUCLEAR COMPLEXES WITH N,N,N' ,N'-TETRABUTYLADIPAMIDE

本文合成了化合物Bu_2 NCO(CH_2)_4 CONBu_2(TBAA),并与稀土硝酸盐制得一系列配合物,其化学式为Ln_2(TBAA)_3 (NO_3)_6 (Ln=La,Nd,Sm,Eu,Gd,Tb,Dy,Tm,Lu)通过元素分析、红外光谱和拉曼光谱等测试研究了该系列配合物有关性质,表明该系列配合物具有相似的红外和拉曼特性,所有的NO_3均为双齿配体.三个有机配体分别以羰基中的氧与两个Ln(Ⅲ)配位,每个Ln(Ⅲ)的配位数为9.

Lanthanide nitrate of N,N,N',N' - tetrabutyladipamide (TBAA)were synthesized. These complexes with the general formula La2μ-(TBAA)(TBAA)2(NO3)6 have been characterized by means of elemental analysis,IR and Raman spectra. It shows that the complexes have similar IR and Raman properties,all nitrates behave as bidentate, two Ln ( Ⅲ ) ions are also coordinated to oxygen atoms from carbonyls of three organic ligands.the coordination number of each In atom is nine.
